Windows 7: File In Use when deleting file

I searched via google and saw that many people have this problem but no definite problem. It says it is in use with explorer but it is not. Do you know any solution without killin explorer exe and delete via cmd command

Give the program Unlocker a shot. Not only is it free and compatible with all versions of Windows from 2000 up to 7, it allows you to "unlock" file handles from processes without terminating them (of course, you are also given the latter option).

This is the only utility I've found to date which allows you to do this (unlock file handles without terminating processes or rebooting a computer).
